Merge branch '13948-access-request-to-projects-and-groups' into 'master'

Allow users to request access to projects and groups

#### TODO:

- [x] Factorize the projects & groups members list
- [x] Factorize `request_access` and `approve` controller methods into a concern
- [x] Factorize the project & group dropdowns
- [x] Factorize access request routes
- [x] Factorize mailers

#### Will be done in separate MRs

- [ ] Documentation
- [ ] API

#### Access request to project

- [x] Design project access request button to spec (defined in #13948)
- [x] Request access to a project as a logged in user
- [x] Withdraw access request to a project as a logged in user
- [x] Do not treat project member request as actual membership (done partly in Ability)
- [x] Display access requests on project's members page (+ allow to change level, approve, and deny request)
- [x] Email requesting user at notification email address when accepted/denied
- [x] Email all project admins at notification email addresses when new access request
- [x] Unit specs to cover new functionality: `AccessRequestable` is missing specs
- [x] Controller specs to cover new functionality
- [x] Mailer specs to cover new functionality
- [x] Features specs to cover new UI and interactions
- [x] Regression specs still passing

#### Access request to group

- [x] Design group access request button to spec (defined in #13948)
- [x] Request access to a group as a logged in user
- [x] Withdraw access request to a group as a logged in user
- [x] Do not treat group member request as actual membership
- [x] Display access requests on group's members page (+ allow to change level, approve, and deny request)
- [x] Email requesting user at notification email address when accepted/denied
